Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...

Forbes contributors publish independent expert analyses and insights. I cover the history of science and exploration. Today's Google Doodle celebrates the 214th birthday of Christian Doppler, whose ...

The Doppler effect is an observed change in pitch (how high or low a sound is) when either the source of the sound or the listener is in motion. Imagine a car, its horn blaring, approaching you as you ...

The International Isle of Man TT is a crazy motorcycle race. I mean—it's seriously ludicrous. They ride on public roads (yes, they are closed to normal traffic) such that you get these videos of bikes ...

Meteorologists and weather experts in South Texas rely heavily on Doppler radar technology, but how does it work? How can a giant soccer-ball-shaped tower, known as the radome, detect clouds hundreds ...

The Doppler effect can be heard particularly clearly when a train passes by. The presence of the same effect in the generalised telegraph equation indicates the wave nature of heat transport over ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

MADISON -- What if the speed of light is a constant only most of the time? What if gravity sometimes pushed instead of pulled? Scientists are increasingly asking what would seem like far-out questions ...

A video of scientists dropping ice into a really deep hole has gone viral because of the wobbly cartoon-spaceship sound the falling ice makes. Princeton University geochemist John Andrew Higgins ...

Ultrasonic flow meters are non-invasive devices that use acoustic vibrations to determine the flow rate of a liquid. There are two types of ultrasonic flow meters – Doppler and transit time. Both ...
